Since the onset of the Cold War, the Republicans have attempted to taint the Democrats as unpatriotic, in league with America's enemies, without and within. With the Cold War's end, one of the central organizing principles of the Republican political strategy dissolved. But in the aftermath of Sept. 11, US President George W. Bush and his political adviser Karl Rove have reanimated the patriot game, and Democrats have been conflated with terrorists and tyrants.
The founding father of the Republican patriot game was the late president Richard Nixon, whose career was borne along by impugning the patriotism of Democratic opponents and uncovering subversives whom he claimed represented the heart of the new deal. His relentless ambition, however, was thwarted when he found himself confronted by a war hero, John Kennedy. In 1960, the game was over. But the Vietnam war gave Nixon the platform for his resurrection. Once he became president, the game of smearing the Democrats was reinvented as he set Vietnam veterans and hard hat, blue-collar workers against war protesters.
